I don't really edit videos too much, but I've found OpenShot to be easy enough to use for basic editing although it's a bit feature-limited. I've heard good things about DaVinci Resolve too, but it does seem more complicated. They're both free and should be able to handle a few transitions, snipping, and other basic editing.

Ah I see, that makes a lot of sense. I guess for that to work you still need it to be on the board one turn later, which isn't guaranteed. Interesting though!
